2 Claims. (Cl. 206-65) This invention relates to cartons and like containers for shipping and storing packages of yarn wound on hollow cores. In particular, this invention relates to a partition in a shipping and storing carton including means adapted to vertically and laterally support yarn packages on cones while maintaining them separate and in layers.

Yarn packages are preferably shipped and stored in a manner to prevent their rubbing and scuffing against one another and against layer separating partitions or against the walls of the carton in which they are contained in order to eliminate damage to the outer layers of yarn on the package. Yarn packages are also frequently placed in cartons by a method using a simple partitions of a type which may have a plurality of spaced openings through which the top or nose portions of the conical package cores in a lower layer extend to jut into the bottom portions of the package cores in an upper layer which are disposed over the apertures. While such partitions serve to space the packages in each layer, the packages generally rest movably upon the end portions of the yarn in the packages of each layer over which a partition is employed. Since such partitions do not usually provide satisfactory lateral support for the yarn packages spaced in layers in the carton the yarn is subject to being scuffed and soiled. Another method is where yarn packages are individually wrapped in paper or other coverings to minimize damage and soiling of the yarn and shipped and stored in cartons by packing them one against the other in layers separated by a plain partition. While in the latter method an improvement is realized to some extent, generally, however, further improved methods require the use of a partition equipped with various type package core supporting inserts which are positioned into apertures of a partition and engage the yarn package cores at their top and bottom portions. Such partitions are comparatively more expensive, and additional labor is required in packaging the yarn.

The present invention provides for a simple partition having a particular type of integral core supporting means which renders positive lateral and vertical support to the yarn packages of each layer in the carton. Special package supporting inserts are not required with a partition in accordance with the present invention, yet the packages may be closely spaced without possibility of contact or movement and securely maintained in layers without any requirement for individual wrapping. In addition, labor and expense are minimized.

In accordance with the present invention, a partition to support and maintain separate in layers packages of yarn on hollow cores packed in cartons and like shipping and storing containers comprises a separator sheet having a plurality of spaced, generally quadrangular apertures having generally square corners with a hinged pair of generally rectangular core engaging flaps, integral with the partition, positioned on the sides of each aperture. The flaps may comprise the cut-out portions of the aperture. Each pair of flaps is adapted to open to admit the top portion of a package core of a lower layer. When the bottom portion of a package core of an upper layer is positioned over the aperture the flaps interiorly engage and laterally support such bottom portion of the upper core while simultaneously exteriorly engaging and laterally supporting the top portion of the lower core. Due to the cooperative effect between the partitions and the packages and the locking action of the flaps being pressed upon the top portion of the lower cores in each aperture by being squeezed in the lower portions of the upper "ice cores, substantial vertical support, as well as firm lateral support, is also given the packages of the layers so that they do not touch one another or move upon the partitions which support them in the carton.

Other advantages and features of the present invention are readily apparent in the following description and the claims.

The accompanying drawing, wherein like reference numerals refer to like parts, represents an embodiment of the partition means in accordance with the present invention, wherein:

Figure 1 is a plan view with the central portion omitted of a partition perforated to form a plurality of spaced apertures providing integral core engaging flaps;

Figure 2 is a plan view with the central portion omitted of a multiwall partition perforated to form a plurality of generally quadrangular spaced apertures providing generally rectangular, integral core engaging flaps;

Figure 3 is a perspective View of a part of a partition taken along section lines 33 in Figure 1 showing one of the apertures formed by opening the integral core engaging flaps;

Figure 4 is a perspective view of a part of a partition taken along section lines 44 in Figure 2 showing one of the generally quadrangular apertures formed by opening the integral, generally rectangular core engaging flaps and a preferred manner of partially perforating the hinged portion of a multiwall partition; and

Figure 5 is a sectional view of part of a yarn package in an upper layer and part of a yarn package in a lower layer being supported and positioned by the partition.

With reference to Figures 1 and 3, a partition 10, utilized to separate layers in a shipping carton (not shown) has a plurality of perforations 11 cut therethrough to conform to the spacing arrangement of yarn packages positioned in superposed layers in a carton. The partition 10 may be of cellulosic corrugated board of single or multiwall construction or of other suitable material. It may assume any flat configuration in order to conform to the cross-section of the carton or other container employed although, generally, as shown, it is square or rectangular.

The perforations may be spaced in any desired pattern or arrangement for the individual yarn packages to be held in the layers. As shown, the perforations 11 are in parallel, equispaced rows although they may be staggered or otherwise arranged if desired. Each perforation in the partition is cut to form a pair of substantially rectangular core engaging fiaps 13 and 14, which as illustrated in Figure 3, are integral with the partition 10 and which may be opened to form the substantially square aperture 12. This may be accomplished by die-cutting, or otherwise suitably perforating the partition with a plurality of cuts resembling the capital letter of H or I. The H-cut or I-cut perforation each yields a pair of juxtaposed, substantially rectangular flaps unsevered or, if desired, incompletely severed along their non-contiguous sides from the partition 10. These flaps are adapted to be hingedly bent open along their non-contiguous sides to form the aperture 12.

When a corrugated board of multiwall construction is employed as a partition it is often advantageous to partially severed the hinge portion of the core engaging flaps so that opening of the flaps is more easily accomplished. Generally, it is preferable to leave the uppermost section only of a multiwall partition unperforated, although any desired portion of the multiwall partition may be perforated along the unsevered portion holding the flap. As shown by Figures 2 and 4, the double wall corrugated board partition 20 has a plurality of perforations 21 cut therethrough. Each perforation forms a pair of generally rectangular core engaging flaps 23, 24 integral with the partition 20 which may be opened up to form the generally quadrangular aperture 22. The hinge portions 25, 26 of the generally rectangular flaps 23, 24 respectively are partially perforated through the lower wall of the par tition 20 to more easily open the flaps. The partial perforation of the hinge portions 25, 26 is along an arcuate partial cut, as illustrated, so that the flap supporting sides of the aperture 22 are slightly arcuate to conform somewhat to the circumference of the nose portions of a package core inserted through the aperture. This construction is often'desirable to improve and more evenly distribute the support of the packages by the partition means.

Obviously, if desired, the apertures of either substantially square or generally quadrangular configuration may be first completely cut out of the partition and the core engaging flaps subsequently affixed hingedly integral with the partition to sides of the aperture by any suitable fastening means such as tape, etc.

As illustrated by Figure 5, a yarn package 15 in a lower layer of yarn packages has the top portion of its hollow conical core 16 extending through one of the apertures 12 of the single wall corrugated board partition 10 to engage the integral core engaging flaps 13, 14. Fitted over the aperture is a yarn package 17 having the bottom portion of its hollow conical core 18 interiorly engaging the flaps 13, 14. As is apparent, the top portion of the core 16 forces the flaps open so that the flap corners are pressed against the interior of the bottom portions of the core 18. The rigid engagement of the fiaps' 13, 14 on the top of the package core in the lower layer and against the interior bottom portion of the package core in the upper layer provides substantial lateral and vertical support to the yarn packages in the layers.

In filling cartons with yarn packages when using partitions in accordance with the present invention, a bottom layer of yarn packages is first placed in the carton in the desired pattern. A spacing means, such as a cardboard sheet having openings to accommodate the core bottoms of the yarn packages in the bottom layer, may be employed for this purpose. A partition member is then placed over the layer of yarn packages with the top portion of the package cores extending through the apertures in the partition holding the core-engaging flaps open. The next layer of yarn packages is then placed in position on the partition with the bottom portions of the package cores over the apertures and locking the flaps in engagement with the interior of the bottom portions of the package cores in the upper layer and the exterior of the top portions of the package cores in the lower layer. The procedure is repeated until the desired number of layers to till the carton is reached when another spacing means for the top portions of the package cores in the uppermost layer may be employed.

Since certain changes in practicing the invention may be made without departing from its scope, it is to be understood that all the foregoing description be interpreted as merely illustrative and in no sense limiting of the invention.
